re: this thread
Will is the one who “completes the set” when his dad instincts kick in and he claims Riven as his unofficial other kid.
Jason is a trans man, Catie is a trans woman, Riven is nonbinary. The whole set! /j
But in the other hand, it works SO WELL for EfHA and ties back into TLS so damn perfectly that I like… HAVE to do it.
Anyway, all that to say that Riven, then NB mc of EfHA, gains an adopted parent (several actually), and they subsequently complete a set for said parent, beknownst to Riven.
